Substrate
Integrated Waveguide – Base for Leaky Wave Antennas
Author: Jan Machac(Faculty
of Electrical Engineering Czech Technical University, Prague, Czech Republic) , (40 min +
40 min for
Q&A)
Abstract : Antennas designed on the substrate integrated waveguide have a planar structure, and can be easily fabricated by a standard PCB technology, so they are suitable for cheap mass production. The lecture presents the results of an investigation of leaky wave antennas designed on a substrate integrated waveguide. The interest is given to three antenna types: an antenna radiating from a wide longitudinal slot etched in the top waveguide wall, a SIW CRLH leaky wave antenna, and a dual band SIW CRLH leaky wave antenna. These two later antennas radiate through meander slots etched in the top metallization which serve as series capacitors added to design the CRLH transmission line

Q&A)
Abstract:
Surface electromagnetic waves (SEW), discovered by Sommerfeld and Zennek
more than a century ago in connection with their search for an explanation
of transoceanic radio communications, have now again become relevant in
photonics problems. Plasmonpolaritons, related to the SEW, have of
practical importance for the integration of fiberoptic communication
channels with electronic microcircuits. The interest in SEW is due to their
ability to propagate with relatively weak attenuation along metallic,
graphite, cylindrical and limited conductors, along open waveguides with
transverse dimensions smaller and comparable to the wavelength, along
conductive plates. Unfortunately, studies of the SEW in the microwave range
of radio waves, with rare exceptions in the form of demonstration
experiments, have not been carried out. The paper presents the results of
experimental studies and analysis of the structure of SEW, their propagation
through a single wire, a conductive tape in the centimeter range of radio
waves, convenient for modeling open waveguides of optical and terahertz
(THz) ranges of electromagnetic radiation.

Analytical solution to the 1D grating diffraction
problem
Author: A. À. Shcherbakov
( Moscow Institute of Physics and Technology, Dolgoprudny,
Moscow Reg.,
Russia ), (45 min + 15 min for
Q&A)
Abstract:
The presentation will show that the use of two rigorous techniques in the
diffraction theory, namely, the Cmethod and the modal method, by
construction of the modal basis for a diffraction problem delivered by a
curvilinear coordinate transformation of the Maxwell’s equations yields a
general analytical solution to the 1D grating diffraction problem in the
Tmatrix form for gratings which profiles are defined by piecewise twice
continuously differentiable functions. Moreover, the constructed basis being
transformed to the initial coordinate system appears to coincide with the
Rayleigh expansion in the grating region.

Method of Fundamental Components in the Physical Theory
of Diffraction
Author: M. V. Vesnik
( Kotelnikov Institute of Radio Engineering and Electronics
RAS, Moscow,
Russia ), (45 min + 15 min for
Q&A)
Abstract:
A novel heuristic method of obtaining heuristic solutions for 3D diffraction
problems (method of fundamental components) is proposed. This approach has
several advantages over the known heuristic methods such as GTD and MEW. The
new method proved to be effective in obtaining of heuristic solutions to a
number of reference problems, such as diffraction on a perfectly conducting
plane angular sector and diffraction on a semitransparent halfplane.
Application of the method provides new possibilities for solving practical
problems such as calculation of the radar crosssection, wave propagation in
urban areas, location of seismic objects using elastic waves..

Abstract:
A kinematic model of a circular orbit satellite group is presented. An
equation for calculation of the number of satellites in the group demanded
for the global Earth coverage by onboard antenna systems with conical scan
sectors is obtained. A simplified method for calculation of the footprints
map on Earth surface formed by the partial radiation patterns of an active
electronically scanned array (AESA) is proposed. Equations for calculation
of the slant range, elevation angle, coverage zone are given. Numerical
examples and graphical illustrations are made to verify the model.

Authors: V.A. Ruchenkov (speaker), V.D.
Teplyakov, A.S. Petrov(Company

Q&A)
Abstract:
Some features of the antenna pattern (AP) forming process occurring in the
schemes of active phased array antenna with analog controlling at radiators
and digital controlling at subaperture level are analyzed. A linear antenna
array example have demonstrated that the interbeam interference takes place
at scanning causing AP's distortion and its angle maximums shift with large
signal amplitude modulation appearance at inputs of radiators. Some methods
to reduce the impact of those effects on the parameters of multiple beam
array and to reduce the level of interference lobes in analogdigital
beamforming schematic are recommended.

Abstract:
Analysis of changes in angular dependence of planar phased array antenna
directivity gain at increasing of the number of radiators was carried and
revealed it filtering property. With the increase of the number of elements,
the angular directivity gain dependence tends to the well known limiting
cosine function but nevertheless differs from it at angular regions where
antenna pattern has zero value as well as at wave grazing angles relative to
the aperture. It was demonstrated that when the radiators are almost
omnidirectional then at about the total angular region of scanning the
limiting directivity gain behavior was observed already for 4 4 array.

Abstract: The twodimensional problem of bifocal, threefocal and fourfocal constrained lens synthesis for symmetrical focal curves is solved. Solution of the problem is reduced to the transcendental equation for the lens shape. On the basis of a numerical solution of the equation the optimization of the parameters and the analysis of the eikonal aberrations of the optimized lens are done for two values of angle of view: 60 and 90 degrees.

Q&A)
Abstract:
Some opportunities of achieving a cutoff radiation pattern in semishadow
area of an antenna by supplementing the ground plane with a system of
semitransparent ribs parallel to the main lobe direction are considered.
Mathematical models are developed, computer simulation is performed, and the
results of simulation are supported by experimental data. It is shown that a
cutoff of about 20 dB is achievable. The results are relevant to

Modeling of the Characteristics of Perfectly Conducting and
Impedance Bodies on the Basis of the Method of Auxiliary Currents
Author: E. S. Negorozhina,
(Moscow Technical University of Telecommunications and Information
Science,
Moscow,
Russia ), (45 min
+ 15 min for Q&A)
Abstract: The
aim of the work was the creation of an effective and universal
numerical method for threedimensional problems of diffraction of
electromagnetic waves by single scatterers in a fairly wide range of
wave sizes, and by a group of bodies. For this purpose there were
used the theoretical foundations of the modified method of auxiliary
currents (MMAC). As a result, we developed a generalization of the
MMAC and its version  modified method of discrete sources (MMDS)
for the problem of diffraction of electromagnetic waves on perfectly
conducting bodies and bodies with impedance boundary condition, as
well as on a group of impedance bodies of revolution. Modeling of
the scattering characteristics on the bodies with nonsmooth
boundary is also considered. A comparative study of the use of
spline bases of various orders for the numerical solution of
integral equations by the modified method of auxiliary splinecurrents
was done. The use of the MMDS for solving diffraction problems in
highly prolate and highly oblate bodies with spheroidal coordinates
Proposed is proposed. Numerical results for simulated problems
characterizing performance of the developed algorithms are presented
and discussed.

(Lianozovo Electromechanical Enterprise, Moscow,
Russia ), (45 min + 15 min for
Q&A)
Abstract:
Definition and specification of the internal and external Huygens cubes in
numerical modeling using universal electromagnetic codes are presented. A
numerical solution to an electromagnetic problem for interior Huygens cube
obtained with the use of the ASYS HFSS v. 15 code is compared to a known
analytic solution. It is shown that, with an increase in frequency, the
accuracy of the numerical solution degrades in both the amplitude and phase.
The frequency characteristics of the external Huygens cube are numerically
simulated and compared with those of the internal Huygens cube. Dependence
of the frequency characteristics of the external Huygens cube on the sizes
of the air cube is analyzed. Radiation patterns of the external Huygens cube
with the edge that is much less than the wavelength, a half of the
wavelength, and of the wavelength are given. The dependence of its pattern
shape on the boundary condition on the second input is shown. The paradox of
the external Huygens cube is noted. The influence of the boundary condition
on the unexcited input on its pattern is considered.

Abstract: A
geometric interpretation is proposed for synthesis of a distribution
system employed in multibeam phased antennas array (PAA).
Relationships are obtained for the angles of deflections of PAA
beams and for optimum positions of the probes of the distribution
system. The optimization is performed according to two criteria: the
minimum mean deflection and the minimum local deflection. The
example of construction of a distribution system is presented.
Dependences of the phase errors on the positions of radiators and

Smooth transitions in waveguides with infinitely thin edges
Author: S. E. Bankov,
(Institute of Radio Engineering and Electronics of RAS, Moscow,
Russia ), (45 min + 15 min for
Q&A)
Abstract: A
problem about coupling coefficients of eigen modes of a closed waveguide
containing structures with infinitely thin metal conductors is considered.
The original structure with thin edges is replaced by a structure with metal
cylinders of a finite radius that then approaches zero. Expressions for
coupling coefficients of waveguide the eigen modes are obtained as a results
of the above mentioned passage to the limit. The proposed approach is
developed also for a case of waveguides with TEM  modes. It is demonstrated
that in the single mode regime the obtained expressions give the same result
as those given by the known theory of transmission lines with variable
characteristic impedance. The technique developed above is applied for
analysis of a twodimensional array of TEM horns radiating in the broadside
direction. Explanation of the effect of a bidirectional radiation from the
array obtained earlier numerically is presented.

Qualitative analysis of evolution of the
electromagnetic field radiated by dipole
Authors: D. V. Sorokovik and V. A. Permyakov, (NRU "Moscow Power Engineering Institute", Moscow, Russia ), (45 min + 15 min for Q&A)
Abstract: Some results of qualitative analysis of the nonstationary electromagnetic field and the power flux density produced by an elementary electric dipole operating in the harmonic and nonharmonic modes as well as by a finite thin dipole operating in the harmonic mode are presented. In the case of pulse excitation, classification of the singular points of the dipole vector field is given, conditions for bifurcation of the field lines are determined, and instantaneous velocities of the dipole field components are analyzed. Nontrivial features of the structure of the dipole near electric field are studied, including the feature that was revealed as long ago as at the end of the XIX century by H. Hertz but has not been interpreted for a long time. Regularities in formation and motion of the singular points of the electromagnetic field of a finite dipole are considered and a relation between trajectories of the singular points and nulls of the radiation pattern is found.

Some features of the overlapped subarrays built up of
beamforming matrices for shaping flattopped radiation patterns
Author: S. P. Skobelev (Company
"Radiophyzika", Moscow,
Russia ), (45 min + 15 min for Q&A)
Abstract: Comparative
analysis of subarray factor shape and array network complexity is
carried out for an approach proposed recently for building up linear
arrays of overlapped subarrays for limited field of view
applications on the basis of beamforming matrices. It is shown that
the flattopped subarray radiation patterns can be shaped only at
the expense of some reduction of the subarray gain at the broadside
direction, and the quality of the flattopped beam shape is almost
independent of the number of array modules in a subarray. Evaluation
of the array network complexity is proposed and evaluated on the
basis of array element use efficiency. Application of the approach
to building up planar overlapped subarrays is addressed and some
results of optimization of the subarray factor are presented.

On the propagation of longitudinal highfrequency and
lowfrequency waves in sea water
Author: V. A.
Atsukobsky
(Moscow
Reg.,, Russia) , (45 min + 15 min for Q&A)
Abstract:
Dynamic forms of the OstrogradskyGauss theorem and the third
Maxwell equation are developed. On their basis, there is shown a
possibility of developing a communication channel using the
longitudinal highfrequency waves in sea water where the Pointing
vector and the electric field strength vector are collinear.
Appropriate equipment was developed and experiments were carried out
in the Black Sea water confirmed the theoretical statements. The
difficulties of matching the receiving equipment inputs in the sea
water at 1 GHz were revealed and overcome. There were obtained
results confirming radio communication at 10 km distance in a
subsurface layer at the depth down to 3 m at practically total
absence of the signal at great depths and in the air. There were
developed the grounds of propagating the highfrequency and
lowfrequency electric waves in sea water with the exception of the
near zone.
2. On the relations between the structures of nonstationary electromagnetic fields and the structures of the exterior sources
Author: V. A. Permyakov (Moscow
Power Engineering Institute , Russia) , (45 min + 15 min for Q&A)
Abstract:
In June 2012, representation of the electromagnetic field described
by nonstationary Maxwell equations as a superposition of vortex and
potential fields was discussed at the Moscow Electrodynamic Seminar.
Usually, application of this representation is justified by
referring to the Helmholtz theorem without discussing its
applicability conditions. It has been shown that the applicability
conditions of the Helmholtz theorem are not fulfilled for
nonstationary fields. In this report, an approach to establishing a
relation between the structures of exterior sources and the
structures of the electromagnetic field excited by these sources,
which is based on the analysis of the continuity equation for
exterior sources from the viewpoint of the set theory, is proposed.
A classification of the structures of exterior sources and fields
excited by these sources, including static, stationary, and
nonstationary fields, is proposed.

transverse waves of magnetic field, as well as some relations
between the indicated waves and their sources are theoretically
justified.
2. Analysis of some experimental results on the "longitudinal" electromagnetic waves from the viewpoint of the classical electromagnetic theory
Author: V. A.
Permyakov (Moscow
Power Engineering Institute (National Research University), , Russia) , (45 min + 15 min for Q&A)
Abstract:
In the last decades there have been carried out some experiments,
the results of which are considered to be a proof of the existence
of the "longitudinal" electromagnetic waves (LEMWs). According to
their authors, the description of the experiments is impossible in
the frame of the classical theory and therefore it requires
generalization of the Maxwell equations. However the study of those
works shows that they don't comprise any comparisons of the
experimental results to theoretical calculations performed according
to the classical theory. Therefore, the claims of the existence of
the LEMWs are not justified. As an example, we carry out the
analysis of the works on radiation of a spherical antenna above the
planar earth surface as well as on propagation of the EMWs between
two horizontal dipoles arranged on the same axis under the water
surface. It is shown that the experimental data can be explained in
the frame of the classical electromagnetic theory.

Abstract:
Three approaches based on the method of extended boundary conditions

the general solution of the complex Maxwell's equations for an
inhomogeneous isotropic periodic finelaminated medium consisting of
two different alternating thin isotropic planar layers at any
wavelength coincides with a general solution of the Maxwell's
equations for an homogeneous anisotropic medium in the form of
singleaxis magnetodielectric crystal of the same thickness as the
initial inhomogeneous medium.

Abstract:
On the basis of the electromagnetic propagation equations for the

dipole antennas effectiveness and optimization methods, showed the
structure of fields, discussed the radiation patterns and ways to
ensure omnidirectional radiation, given estimates of the
communication range and the results of experiments and examples of
practical design. Although the communication range and information
rate increase significantly when approaching the receiving and
transmitting antenna to the ocean surface, especially in the cases
of small depth near the shore, the focus of the report will be given
to the occasion due to great depths, when the influence of the
surface can be neglected. This case is not considered much in the
professional electrodynamical literature, especially in Russian one.
The author will try to explain why the terms «near zone» and

Surface electromagnetic waves guided by planar boundaries of
highly conductive media  Zenneck wave
Author: V. V.
Shevchenko
(Kotel'nikov Institute
of Radioengineering and Electronics of RAS , Moscow, Russia) , (45 min + 15 min for Q&A)
Abstract:
The properties of a theoretical model of surface electromagnetic
waves guided by planar boundaries of highly conductive media such as
metals, humid soils, sea and salty water in general are considered.
The phase, group, and energy flow velocities of these waves are
calculated. These waves are related to the unusual type of waves,
the âroup velocity of which is differed from the energy flow
velocity, that is the velocity of wave energy transport.
Although depending on the medium parameters, the phase and â group
velocities of these waves can be higher than the velocity of light,
their energy flow velocity is always lower than the velocity of
light. The socalled Zenneck wave is related to the considered type
of waves.
2. Surface electromagnetic waves  Experimental confirmation of the SommerfeldZenneck theory
Author: V. N. Datsko
( Moscow Institute of
Electronic Technology, Moscow Region, Russia) , (45 min + 15 min for Q&A)
Abstract:
At the beginning of the 20th century, surface electromagnetic waves
(SEV) were predicted by German scientists A. Sommerfeld and D.
Zennek. But their findings were disputed by the world experts, and
the surface waves could not be found in largescale field
experiments carried out in various countries. By the middle of the
20th century there was formed a strong opinion of nonexistence of
the SEV (except for surface acoustic waves). However, in the 60 's,
some theoretical works on the SEV appeared, of which the most
substantial ones were published in the USSR. In 7080s the groupÂ»
of experimenters in Mendeleyevo, Moscow Region, investigated the SEV
in a longterm series of laboratory experiments including the SEV in
salty water of different concentration, in gas and semiconductor
plasma, as well as in metals. The experiments confirmed the base
properties of the surface electromagnetic waves predicted by
Sommerfeld and Zennek.

Application of orthogonal expansions in the antenna and
photonic
technology
Author:  V. I.
Gusevsky
(Design Bureau of the
Moscow Power Engineering Institute, Russia) , (45 min + 15 min for Q&A)
Abstract:
Author considers a new approach to the application of orthogonal
expansions of electromagnetic fields in linear and planar antenna
apertures of arbitrary shape and with amplitude distribution of
general form.
The main feature of this method is that a positive function of the
amplitude distribution of the main polarization component of the
field within the antenna aperture is used as a weight function that
generates a sequence of orthogonal functions.
In this case, the phase field perturbations are described by
orthogonal harmonics, which acquire the properties of eigen
functions of an integral operator, transforming the set of the
orthogonal field harmonic in the antenna aperture into many antenna
patterns in the far zone.
It is shown that this approach has allowed solving a number of new
problems of the antenna technology. In particular, there have been
realized the procedure of electoral suppression (or increase) of the
level of the specified side lobes of the antenna pattern in the far
zone. Through the formation of sector deeps the problem of
suppression of the broadband noise is solved. There is solved the
problem of minimization of the slope of the phase characteristic of
the main lobe of the antenna pattern. A way to control the shape of
the antenna pattern in the reflector antennas with passive
scatterers is proposed.

in phased array antennas
Author:  S. P.

Company
"Radiophyzika", Moscow, Russia , (25 min + 15 min for Q&A)
Abstract:
Quantitative analysis of effectiveness of using noncoupled
largeaperture radiating elements in planar singly and doubly
periodic phased antenna arrays is carried out. The indicated
effectiveness is defined as a ratio of the minimum number of
elements necessary for satisfying requirements specified for the
array gain within a specified field of view to the actual number of
the largeaperture elements. It is shown that in each case there
exists an optimal relation of the actual array element spacing to
the maximum possible element spacing corresponding to the specified
fieldofview width providing maximum of element use effectiveness.
It is found that a higher (by 4to5%) effectiveness is achieved
when using apertures with tapered amplitude distributions.

Abstract:
Two types of multibeam offset dualreflector antennas (MBRAs) are
considered. Calculated characteristics of bifocal antennas and
antennas with classical surfaces with nonconventional optical design
are presented. A novel procedure for designing of threedimensional

BFRAs with a wide field of view is described. As an example, four
BFRAs designs are presented. One of them has a50Â° field of view and
a directivity of higher than50 dB. As the MBRAs withtwodimensional
